IMPROVEMENT IN OYSTER'WINDERS.

Specification forming part of Letters Patent No. 136,737, dated March 11, 1873.

To all whom it may concern:

Be it known that I, WILLIAM H. KANNE, of the city of Baltimore, county of Baltimore and State of Maryland, have invented an Improved Oyster-Winder for dredging oysters 5 and I do hereby declare the following to be an exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification, in which- Figure I represents a side elevation of the machine to be attached to a boat; Fig. 2, an end view of the same. Fig. 3 isa top view of the curved rack that. gears into the teeth of the iiauge of the cylinder, the iiauge as shown at Fig. 4. Fig. 5 represents the inside of the pulley or grooved wheel with` its llockingblocks.. v

The nature of my invention consists in the construction of the upright locking-leven clutching the. pulley, moving and shifting it backward and forward, and arranged with the rack at top and weight below to lock or unlock the windlass that is self-reversing, wit-hout carrying back or revolving the crank, thus preventing injuryto the operator while dredging for oysters.

A represents the frame B, the windlnss or cylinder; C C, the cranks; A(D, the upright 1ever with its weight E below, and gearing and ungearin g v,oval frame Gv at top. H H are sliding -pins on the inside of the oval frame G that fit into the groove J of thegearing-pulley K, the pulley K revolving with the axle L of the windlass B, and sliding backward and fort ward on the projecting-guide M on the axle L. N is a cog-gearin g attached to the outside of the ange of the cylinder'B, into which the teeth of the curved rack P at top gear. The rack P also operates and revolves upon a pivot at the top of the frame Gr. There are twoV square-looking blocks, R B, on the one side of the flange of the windlass B and inside of the circle of the cogs or teeth N, and two corresponding locking-blocks S S on the inside of the pulley K that fit in between the blocks It R so as to lock `the windlass when required.

The lever D operates on a fulcrum, V, on the inside of the frame A, and operates the pulley K at top by the pins H H moving and shifting the pulley backward and'forward and locking or unlocking the windlass, when required, by the draw of the weight E upon the lever D, which prevents the crank from being rapidly revolved or dying backward and injuring lass reverses the windlass, the rack P is thrown back and out of gear, and the rope unwinds with the revolving windlass that revolves looselyv and independently of the axle or shaft L without carrying back or revolving the crank 0 that remains still and stationary in the hands of the operator.

What I claim as my invention, and desire to secure by Letters Patent, is-V The combination of the upright locking and unlocking lever D with its oval frame G, pins H H operating in the groove of the shiftin g-pulley K, and curved rack P gearing into the teeth N of the loose and reversible wind. lass B and the locking-blocks R R and S S, when constructed, arranged, andI operating as herein described, and for the purpose of dredging oysters, as set forth.
